Juggles the clown stands on one end of the teeter-totter at rest on the ground. Bangles the clown jumps off a platform 2.3 m above the ground and lands on the other end of the teeter-totter, launching Juggles to the air. Juggles increases to a height of 3.3 m above the ground, at which point he has the similar amount of gravitational potential energy as Bangles had before he jumped, supposing both potential energies are measured by using the ground as the reference level. Bangles' mass is about 80 kg. Determine the mass of Juggles?
